So ready for a President that can move beyond either self praise or put down to one who will focus on the debt & deficit that have gone wild under his time in office. Spending 27% above Obama & deficits even higher. It’s time for a change. https://t.co/oghlZQxAfL

Trump on Tuesday branded Sanford and two other GOP challengers the “Three Stooges.” He also poked fun at Sanford for jetting to Argentina to be with his mistress when he famously claimed he was hiking on the Appalachian Trail in 2009 as his marriage imploded.

Along with Sanford, ex-Massachusetts Gov. William Weld and onetime Tea Party firebrand Joe Walsh are challenging Trump in the primary.

GOP heavyweights like Sen. Mitt Romney (R-Utah) and ex-Ohio Gov. John Kasich say they will sit out the race despite criticizing Trump.

Trump boasted that he isn’t worried about the intramural spat and for once the fact-challenged guy in the White House has a point. Even as his approval ratings sag among all Americans, Trump remains historically popular among GOP voters.
